Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“We were stopped at a stoplight. As soon as we stepped on the gas pedal, there was a loud clunk sound and plastic parts started flying out from under the car. We immediately pulled over. Oil was spilling out everywhere. The transmission oil pump was laying on the inside of the engine compartment. We had towed to Toyota. They diagnosed a bent piston went through engine which also caused a hole in the transmission. I had it towed for a 2nd opinion. Neither toyota or the 2nd opinion had ever seen anything like it. …”
NHTSA complaint #11730547, filed 2026-04“Both front struts of the vehicle have failed and are leaking. There is only 36,000 miles on this vehicle when they should last 200,000 miles per Toyota's service department. Toyota refuses to acknowledge this is their problem and that it's a wear and tear' part. However clearly these parts should not fail after so little usage.”
